Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a new type of vertical corn picking roller with good performance. Background Technology
[0002] Nowadays, the harvesting of crops, such as corn, is mostly done using automated crop harvesting equipment, such as corn harvesters that harvest both stalks and ears, which can improve the harvesting efficiency of corn. Vertical header harvesters are increasingly used due to their high harvesting efficiency. Among them, the vertical ear-picking roller is a key component of crop harvesting, and its structure and performance are closely related to the harvesting efficiency and quality. Currently, most vertical ear-picking rollers in existing technology use a combination of four-sided and eight-sided rollers to harvest both stalks and ears. However, for stalk separation, most current vertical ear-picking rollers rely on feeding the stalks to quickly reach the top of the ear-picking roller, which may cause the stalks to get tangled in the roller, affecting harvesting efficiency. In other words, the harvesting efficiency and quality of the ear-picking roller mainly depend on the speed at which the ear-picking roller pulls the corn stalks and the stability of the corn stalks after they are in place. If the pulling speed is too slow, it will affect the harvesting efficiency. If the corn stalks continue to move upwards after they are in place, they are likely to damage the ears and get tangled in the ear-picking roller.
[0003] Therefore, existing technologies need further improvement and enhancement. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies and solve problems such as low efficiency, poor harvest quality, and inconvenience in using vertical harvesting rollers during crop harvesting.
[0005] This utility model provides a novel vertical corn picking roller with good performance. The vertical picking roller includes a first roller body and a second roller body. The first roller body is a square prism and the second roller body is an octagonal prism. The first roller body and the second roller body are vertically arranged. The corner area of the first roller body is provided with long ridges in the vertical direction. The corners of the second roller body are provided with short ridges at even intervals in the vertical direction. Protrusions and spiral ribs are provided between the short ridges and between the long ridges. The number of protrusions on the first roller body from top to bottom is less than the number of protrusions on the second roller body from top to bottom. A groove is provided below the protrusions of the first roller body and grooves are provided on both sides of the protrusions of the second roller body.
[0006] In a preferred embodiment of this application, the picking roller also includes a lower section roller, which is connected to the bottom of the first roller body and the second roller body respectively. The surface of the lower section roller is evenly spaced with serrations, and spiral ribs are provided at the lower end of the roller body between the serrations.
[0007] In a preferred embodiment of this application, the groove of the second roller is formed on the roller surface of the second roller, and the groove is a square structure in the shape of a concave character.
[0008] In a preferred embodiment of this application, the protrusions are arranged in a vertical direction, and the spiral ribs are arranged around the top of the first roller and the second roller at uniform intervals.
[0009] In a preferred embodiment of this application, the groove of the first roller body and the protrusion of the first roller body are collinear.
[0010] In a preferred embodiment of this application, the first roller body has four rows of protrusions, the second roller body has eight rows of protrusions, and a groove is provided between each adjacent row of protrusions on the second roller body.
[0011] In a preferred embodiment of this application, the two sides of the short ridge are a protrusion and a groove, respectively, and an auxiliary rib is vertically arranged below the protrusion of the short ridge near the second roller.
[0012] The beneficial effects of this utility model are as follows: By separately setting long and short ridges on the first and second rollers, this application not only improves the squeezing effect between the first and second rollers through the setting of the ridges, ensuring the rapid upward movement of the straw, but also, the setting of the short ridges acts as a reinforcing rib, further increasing the friction in the area above the picking roller, thereby improving the ability to squeeze and pull the straw, allowing the straw to be quickly squeezed and moved backward by the picking roller, and obtaining corn ears; furthermore, by setting the number of protrusions on the first roller to be less than the number of protrusions on the second roller, this application not only achieves a similar effect to the long and short ridges, improving the efficiency and quality of ear picking, but also... The fewer protrusions also reduce the processing cost of the picking roller. Furthermore, this application includes a groove structure. During harvesting, the straw surface enters the groove due to the squeezing action of the picking roller, increasing the roller's friction and further accelerating the pulling speed of the straw, allowing it to pass through the roller more quickly and improving harvesting efficiency. Moreover, the spiral ribs not only further enhance friction and ensure picking efficiency, but also act as a barrier and limiter during the straw's upward movement, preventing it from tangling on the top of the picking roller and affecting normal picking operations, thus ensuring both picking efficiency and quality.

[0025] like Figures 1 to 3 As shown, this utility model provides a novel vertical corn picking roller with good performance. The vertical picking roller includes a first roller body 1 and a second roller body 2. The first roller body 1 is a quadrangular prism, and the second roller body 2 is an octagonal prism. The first roller body 1 and the second roller body 2 are vertically arranged. The corner 12 area of the first roller body 1 is provided with long ridges in the vertical direction. The corner 12 of the second roller body 2 is provided with short ridges 21 evenly spaced vertically. Protrusions 14 and spiral ribs 15 are provided between the short ridges 21 and between the long ridges. The number of protrusions 14 on the first roller body 1 from top to bottom is less than the number of protrusions 14 on the second roller body 2 from top to bottom. The protrusions 14 of the first roller body 1 are provided with grooves 16 below them, and the protrusions 14 of the second roller body 2 are provided with grooves 16 on both sides.
[0026] Among them, such as Figure 1 and Figure 2 As shown, the main structure of the vertical ear-picking roller is similar to that of the vertical ear-picking roller in the prior art. In addition to the first roller body 1 and the second roller body 2 at the top for ear picking, a lower roller 3 is connected below the two. The lower roller 3 is a stem-pulling roller. The connection structure between the two and the specific construction of the lower roller 3 can refer to the structure of the vertical ear-picking roller in the prior art. The sprocket, stem-pulling plate saw teeth and other structures in the prior art are also provided in this application. Since these structures are not the main technical features of this application, they will not be described in detail here.
[0027] Furthermore, such as Figure 2 and Figure 3 As shown, the protrusion 14 consists of multiple arc-shaped protrusions, and the structure of the spiral rib 15 is as follows: Figure 1 As shown, it is spiral-shaped. Due to the separation of the long edge 11 and the short edge 21, the spiral rib 15 has a segmented structure, which is used to limit the straw at the top.
[0028] Optionally, such as Figure 1As shown, the ear-picking roller also includes a lower roller 3, which is connected to the bottom of the first roller body 1 and the second roller body 2 respectively. The surface of the lower roller 3 is evenly spaced with serrations 31, and spiral ribs 15 are provided between the lower sections of the serrations 31. It can be understood that the serrations 31 here are similar to the serration structure of the stem-pulling plate in the prior art. The spiral rib structure 15 at the bottom of the lower roller 3 can increase the friction of the lower roller 3 and limit the downward movement of the straw during ear picking.
[0029] As a preferred embodiment of this application, such as Figure 3 As shown, the groove 16 of the second roller body 2 is formed on the roller surface 13 of the second roller body 2. The groove 16 has a U-shaped square structure. Taking the second roller body 2 as an example, the structure of the groove 16 is as follows: Figure 3 As shown, its structure consists of two square grooves arranged side by side to further increase the roller surface 13, improve the pulling ability on the straw, and ensure that the straw can move faster; the groove 16 of the first roller body 1 can adopt a structure similar to the groove 16 of the second roller body 2, or it can adopt a structure as shown in the figure. Figure 1 The structure of the three grooves 16 at the first roller 1 shown is not only aesthetically pleasing, but also can further improve the friction by using a structure that is different from the groove 16 structure of the second roller 2.
[0030] Furthermore, such as Figure 1 and Figure 3 As shown, the protrusions 14 are arranged vertically, and the spiral ribs 15 are arranged around the top of the first roller 1 and the second roller 2 at even intervals. It can be understood that the vertically arranged protrusions 14 have a similar effect to the ridges, which is to improve the friction ability. The protrusions 14 and the straw are squeezed together in a point-to-surface manner. During the operation, the protrusions 14 will be squeezed into the interior of the straw stem, which will strengthen the pulling ability of the straw.
[0031] Furthermore, the groove 16 of the first roller body 1 is collinear with the protrusion 14 of the first roller body 1. As mentioned before, the multiple protrusions 14 stretched into a row can actually be regarded as another level of ridge or reinforcing rib, thereby increasing the friction between the first roller body 1 and the second roller body 2 and increasing the speed of pulling the stalk. By setting the groove 16 of the first roller body 1 and the protrusion 14 of the first roller body 1 to be collinear, compared with directly setting a whole line of protrusions 14 or a whole line of protruding ridges, the cooperation between the protrusions 14 and the groove 16 can make the surface structure of the first roller body 1 more diverse. Moreover, the structure of the groove 16, compared with the ridge, allows part of the straw to sink into the groove 16 during the pulling process, making it easier for the picking roller to pull the straw, thereby further increasing the speed of pulling the straw and thus improving the efficiency of picking the straw.
[0032] Furthermore, as a specific implementation, the first roller body 1 has four rows of protrusions 14, the second roller body 2 has eight rows of protrusions 14, and a groove 16 is provided between each adjacent row of protrusions 14 of the second roller body 2.
[0033] Among them, from Figure 2 and Figure 3 As can be seen, the protrusions 14 are arranged in different numbers and positions on the first roller body 1 and the second roller body 2. On the one hand, this can adapt to the different structural forms of the first roller body 1 and the second roller body 2. On the other hand, the protrusions 14 and grooves 16 on the second roller body 2 are staggered, which can make full use of the more roller surfaces 13 of the second roller body 2 to arrange more friction structures such as protrusions 14 and grooves 16, thereby improving the friction between the first roller body 1 and the second roller body 2 during harvesting, which can also increase the pulling speed of straw and thus improve the harvesting efficiency.
[0034] Furthermore, from Figure 3 As can be seen, for the second roller 2, short ridges 21 are located at the edges of corners 12, and protrusions 14 are located at corners 12. Between the two short ridges 21, the arrangement of protrusions 14 and grooves 16 is protrusion 14, groove 16, protrusion 14, groove 16. It can be seen that the two are staggered, which makes the surface structure of the second roller 2 more uneven, thus further increasing the friction and ensuring the pulling speed of straw and the efficiency of harvesting both stems and ears. During the movement, the first roller 1 rotates counterclockwise, and the second roller 2 rotates clockwise. The spiral ribs 15 of the first roller 1 and the second roller 2 rotate in opposite directions.
[0035] Similarly, such as Figure 2 As shown, an auxiliary rib 22 is vertically arranged below the protrusion 14 near the short rib 21. The auxiliary rib 22 can make the surface structure of the second roller body 2 more uneven, thereby further improving the working efficiency.
